ABSTRACT:
A method for recovering hydrocarbons from a subterranean hydrocarbon bearing formation comprises the steps of providing a production well penetrating in the formation and a plurality of injection wells surrounding the production well. Water is injected into the formation through the injection wells to produce a water flood barrier ringing the production well. A mixture of nitrogen and carbon dioxide gas is injected through the production well and into the formation with the water barrier acting to inhibit the escape of the gas from the portion of the formation surrounding the production well. Gas is injected through the production well into the formation until the formation is pressurized and then gas injection is ceased and the mixture of hydrocarbons and injection gas flowed from the formation through the production well.
